I completely agree. The biggest difference I have noticed, ironically, is while loading _google+_ (try it, firefox 10/11 is faster). The only reason I would use chrome over firefox is because of the incognito mode. I like randomly opening a page in incognito mode without losing my current session.

I do use FF every once in a few days, I just find its start up time irritating (the difference is on the order of seconds). I will say that it definitely has improved though, and I do like the way FF manages tabs over Chrome, but Chrome just feels more pleasant to use
